The weather in Poland, particularly in Warsaw, can be described as "Central European."
According to the weather forecast in Warsaw, during winter, the temperature rarely drops below -5 degrees Celsius, while in summer, it rarely rises above +23°C.
When planning a trip to Poland, keep in mind that there can be occasional light frosts in early spring, so be sure to pack warm clothing. If you're traveling to Poland in autumn, the weather in Warsaw for 3 days in September or October may pleasantly surprise you with warm days.
Unfortunately, the "moderate" capital of Poland is not spared from cataclysms. Although the summer is comfortable enough, find out what the weather promises in Warsaw for the 5 days for which you plan to travel. For example, in early August 2014, the city was hit by heavy rains that flooded the subway and caused huge traffic jams.
However, storms and other climatic disasters are rare here. The main thing is to make sure that the weather in Warsaw for a week of vacation does not prepare for you such surprises as, for example, a snow trap in winter (the most frosty and snowy is January).
When is the best time to go to Warsaw? If you're wondering when it's cheaper to go to Warsaw, the best way to save money is to arrange a tour at a non-holiday time. If it's a 2-3 day trip, get out on the weekend - some museums have free admission on Sunday (like the Royal Palace). But be prepared to be very crowded on those days.
Of course, the Polish capital will offer the most impressions during the summer, when the local parks are fragrant and riverboats cruise along the Vistula River—it's the perfect time to decide, "I'm going to Warsaw!" But the answer to the question of whether it's worth visiting Warsaw in winter is also affirmative. During this time, there are observation decks, indoor zoos, museums, cozy cafés, and nightclubs operating here as well.
